start by reading the ultimate index, understand how your wii and modding works, then go to recommended sectioin as you will find a guide which tells you step by step how to install softmods to play even out of region games.
good luck for now

edit: this could be done in half an hour but you should read a lot stuff before you start so you won't turn your wii into a brick, you ll find everything you need here on the site to avoid bricking your wii.
hints: bootmii as boot2 installed, priiloader
